The Strap Code is a quick set key that sets many
modem parameters. Consult the strap code guide for
available strap codes. Parameters set by strap code:
Data Rate
Inner Code Rate
Satellite Framing
Scrambler
Drop and Insert
Outer Code Rate (Reed-Solomon)
Modulation
Network Spec
{50 – 90 MHz, 100 – 180 MHz,
or 950 – 1750 MHz (L-Band)}
Allows the user to enter the Modulator IF Frequency in 1
Hz increments.
{NORMAL INVERTED}
Allows the user to invert the direction of rotation for PSK
Modulation. Normal meets the IESS Specification.
{QPSK, BPSK, OQPSK, 8PSK, 16QAM}
Allows the user to select the demodulation type.
{INTELSAT}
Allows the user to set the spectral shape of Tx Data
Filter.
{±0 to 255 kHz}
Allows the user to set the acquisition range for the
demodulator
